IMPORTANT CHARGING NOTES
1. After normal usage, your battery pack should be fully charged in
6 to 9 hours. If the battery pack is run-down completely, it may
take up to 9 hours to become fully charged. Your battery pack
was sent from the factory in an uncharged condition. Before
attempting to use it, it must be charged for at least 9 hours.
2. DO NOT charge the battery pack in an air temperature below
+40°F(+4.5°C), or above +105°F (+40.5°C). This is important and
will prevent serious damage to the battery pack. Longest life and
best performance can be obtained if battery pack is charged
when air temperature is about 75°F (24°C).
3. While charging, the charger may hum and become warm to
touch. This is a normal condition and does not indicate a
problem.
4. If the battery pack does not charge properly—(1) Check current
at receptacle by plugging in a lamp or other appliance. (2) Check
to see if receptacle is connected to a light switch which turns
power off when you turn out the lights. (3) Move charger and
battery pack to a surrounding air temperature of 40°F (+4.5°C) to
105°F (+40.5°C). (4) If the receptacle and temperature are OK,
and you do not get proper charging, take or send the battery
pack and charger to your local Black & Decker service center.
See Tools Electric in yellow pages.
5. The battery pack should be recharged when it fails to produce
sufficient power on jobs which were easily done previously. DO
NOT CONTINUE using unit with its battery pack in a depleted
condition.
6. The battery pack will reach optimum performance after being
cycled 5 times during normal usage. There is no need to run the
battery pack down completely before recharging. Normal usage
is the best method of discharging and recharging the battery
pack.
Preparing Your Alligator Lopper TM For Use
WARNING: Read and understand all instructions. Failure to
follow all instructions listed below may result in electric shock, fire
and/or serious personal injury
WARNING: Sharp moving blade. To prevent accidental
operation, ensure that the battery is disconnected from the tool
before performing the following operations. Failure to do this
could result in serious personal injury.
CAUTION: Sharp moving blade. Always wear protective
gloves when installing or removing the chain. The chain is sharp
and can cut you when it is not running.
Chain tension adjustment (fig. E )
WARNING: Before chain or other adjustments, make sure
that the battery is disconnected from the tool.
If the chain cannot be correctly tensioned, it may need to be
replaced. Contact your nearest service center.
The product comes ready assembled. However we recommend that
you check the tension of the chain, and chain retention bolts before
use and if required adjust.
Checking and adjusting the chain tension (fig. E)
To tension the chain slacken the two chain cover retention bolts (11)
with the wrench (12) and the chain tensioning device will push the
chain bar out, setting the correct tension. Retighten the two
retention bolts (11) securely.
Check that the correct tension has been set by lightly pulling on the
chain. The tension is correct when the chain snaps back after being
pulled 1/8 inch (3 mm) away from the guide bar. There should be no
"sag" between the guide bar and chain on the underside.
Note: Do not over tension the chain as this will lead to excessive
wear and reduce the life of the bar and chain. It will also lead to
reduced product performance.
Note: With first use and when the chain is new, check tension
frequently as a new chain stretches slightly.
Replacing the chain and chain bar
After prolonged use the chain and / or chain bar may need
replacing. Use Black & Decker replacement chain RC600 only.
Low-Kickback saw chain is a chain which has met the kickback
performance requirements of ANSI B175.1 when tested on the
representative sample of chain saws.

- Replace the chain access cover (13) and retention bolts (11)
tightening securely.
Operation
Never operate a chain saw that is damaged or improperly adjusted or
that is not completely and securely assembled. Be sure that the saw
chain stops moving when the power control system triggers are
released. Never adjust the guide bar or saw chain when the engine is
operating.
WARNING: Let the tool work at its own pace. Do not overload.
- Carry out regular cleaning of the unit as described in the
maintenance section and in particular cleaning inside the chain
access cover.
- The lower guard jaw (2) and top jaw (1) are designed to close
when one of the handles is released or when the piece of branch
being cut has been cut. If this does not occur, discontinue use of the
tool and remove the battery pack. Check if any debris is blocking
movement. To help in this process it may be necessary to remove
chain access cover(13). If on assembly the problem is still present
take the unit to a service center.
Oiling (fig. I)
A high quality bar and chain oil or SAE30 weight motor oil should be
used for chain and bar lubrication. The use of a vegetable based bar
and chain oil is recommended when pruning trees. Never use waste
oil or very thick oil. These may damage your chain saw.
- Before first use and every ten minutes of use you must oil the
product with the recommended chain oil. Open the oiling cover (4)
and insert the bottle into the oil filling hole (16) apply pressure to the
bottle once to dispense oil.
- This should be adequate for about 10 minutes of cutting
depending upon cutting speed and type of wood.
- The hole feeds the oil through to the chain onto the chain bar and
an excessive amount of oil applied to the unit could mean the oil
drips from the unit around the jaw area. This is normal and is
nothing to be concerned about.
Removing the saw chain & chain bar (figs. F&G)
WARNING: Before chain or other adjustments, make sure
that the battery is disconnected from the tool.
WARNING: Laceration hazard. Always wear protective gloves
when installing or removing the saw chain. The saw chain is sharp
and can cut you when it is not running.
WARNING: Burn hazard. The chain guide bar and chain may
become hot during use. Allow to cool before adjustment or removal.
- Place the tool on a firm surface.
- Rotate the two retention bolts (11) counter clockwise with wrench
(12) provided and remove completely.
- Remove the chain access cover (13).
- Open the handles and pull back the top chain cover jaw (1).
- Pull back chain bar (3) and then lift the saw chain (14) out of the
groove in the guide bar. The chain (14) can then be removed from
the unit.
- The chain bar can then be angled up.
Assembling the chain bar and chain (figs. G&H)
WARNING: Before chain or other adjustments, make sure
that the battery is disconnected from the tool.
WARNING: Always wear protective gloves when installing or
removing the saw chain. The saw chain is sharp and can cut you
when it is not running.
- Ensure the operation is carried out on a firm surface.
- Open the handles and pull back the top jaw (1).
- Insert the chain bar into the space between the chain tensioner
and align with the chain bar locator, angle the chain bar down
ensuring it is correctly located.
- Place the chain (14) around the front of the chain bar and engage
in the nose sprocket of the chain bar. Make sure chain is installed
properly, with the cutting teeth facing forward as shown here.
- Pull the chain bar and chain back, engaging it in the groove in the
chain bar and then over the sprocket (15) positioning teeth in the
correct position on the sprocket.
